Mine ran hot until I gave it a lot more timing at idle, which of course meant I had to limit the total.
I ended up plugging the vac advance into manifold vacuum, and tuning from there.
10° initial doesn't sound like enough...
The OP stated it ran cool enough at idle, but would creep up to 220 at cruise. That's what got me thinking if he was using vacuum advance or not.
I don't think that is what the OP said; "Car still runs warmer then I'd like at slow speeds or at red lights. On a 80 degree day if you keep the car moving @ 45+mph its not to bad. It will run 195 to 200 degrees with a 160 degree Napa Super Stat. At lower speeds 210 to 220 degrees."
